Which of the following is equivalent to the midpoint between the points (7,4) (9,-1)

(fraction 3/2, -8)
(fraction 3/2, -8)
(-8, fraction 3/2)
(8, fraction 3/2)

(8, fraction 3/2)

Step-by-step explanation:

The formula for determining the midpoint of a line is expressed as

[(x1 + x2)/2 , (y1 + y2)/2]

Where

x2 represents final value of x on the horizontal axis

x1 represents initial value of x on the horizontal axis.

y2 represents final value of y on the vertical axis.

y1 represents initial value of y on the vertical axis.

From the information given,

x2 = 9

x1 = 7

y2 = - 1

y1 = 4

Therefore,

Midpoint = [(7 + 9)/2 , (4 - 1)/2]

Midpoint = (16/2, 3/2)

Midpoint = (8, 3/2)

the answer is 8.64
